Description

Aperiodic SRS sending method and related equipment
Technical Field
The present application relates to the field of communications technologies, and in particular, to an aperiodic SRS sending method and a related device.
Background
A Sounding Reference Signal (SRS) is a signal sent by a terminal device to an access network device such as a base station, and is used for the access network device to estimate uplink channel quality according to the SRS and schedule transmission resources. In a Long Term Evolution (LTE) system, SRSs are divided into two time domain types, namely, periodic SRS (Periodic SRS) and Aperiodic SRS (Aperiodic SRS), and in a New Radio Access Technology (NR) system, semi-persistent SRS (semi-persistent SRS) is added, for all three time domain types of SRS.
The SRS may be transmitted based on a certain SRS Resource (SRS Resource), and one SRS Resource is determined by a plurality of Resource parameters configured by Radio Resource Control (RRC), where the Resource parameters may be the number of antenna ports, the number of Orthogonal Frequency Division Multiplexing (OFDM) symbols, a Frequency domain position, a slot position, and the like. A plurality of SRS resources of the same time domain type may constitute an SRS resource set (SRS resource set).
The aperiodic SRS is Downlink Control Information (DCI) sent to the terminal device through the access network device, and the DCI triggers the terminal device to send the Information. For the aperiodic SRS resource set, one slot offset (slot offset) uniquely corresponding to each is configured by RRC. After the terminal device receives the DCI, it may acquire an SRS resource set triggered by the DCI, a slot offset in its corresponding RRC configuration, and further determine a transmission slot for transmitting the aperiodic SRS. In this way, the terminal device can only determine the transmission slot of the aperiodic SRS according to the fixed slot offset in the RRC configuration for the SRS resource set, that is, after the RRC configuration, the slot offset of any terminal device for transmitting the aperiodic SRS for the SRS resource set is fixed and consistent, and this way of determining the SRS transmission slot is relatively single.

The following describes an aperiodic SRS transmission method provided in an embodiment of the present application. The aperiodic SRS transmission method provided by the embodiment of the present application may be implemented based on the system architecture in fig. 1. Referring to fig. 2, fig. 2 is a flowchart illustrating an aperiodic SRS transmission method according to an embodiment of the present application, where as shown in the figure, the method may include steps S201 to S202.
S201, the first terminal equipment receives a first control instruction.
Wherein the first control instruction is an instruction for triggering the first terminal device to transmit an aperiodic SRS. In one implementation, the first control instruction may be DCI, and parameters carried in the DCI may exist in the DCI in a domain form, for example, the DCI may include an SRS request (SRS request) domain, a Time Domain Resource Allocation (TDRA) domain, and the like.
The first control instruction comprises a first parameter domain, and the first parameter domain comprises a first time slot offset. In one implementation, the first control instruction indicates, by means of an explicit indication, a slot offset for the first terminal device to transmit the aperiodic SRS, so that the first parameter domain may be a domain dedicated to dynamically and flexibly indicate, in the first control instruction, the slot offset for the user terminal to transmit the aperiodic SRS, and the first slot offset in the first parameter domain is a slot offset dedicated to transmit the aperiodic SRS; in another implementation, the first control instruction indicates, in an implicit specified manner, a time slot offset for the first terminal device to transmit the aperiodic SRS, where the first parameter domain may be a TDRA domain, and the time slot offset in the TDRA domain may be used to indicate a time slot offset of a Physical Uplink Shared Channel (PUSCH) or a Physical Downlink Shared Channel (PDSCH), where the time slot offset is used to indicate the time slot offset for transmitting the aperiodic SRS.
The first control instruction further includes SRS resource set information, where the SRS resource set information is indication information corresponding to SRS resource sets, and indicates the access network device to trigger which one or more SRS resource sets the first terminal device sends the aperiodic SRS, that is, the first user terminal may determine which SRS resource set is triggered according to the SRS resource set information in the first control instruction. In an implementation manner, the SRS resource set information may be a parameter in the SRS request domain in the first control instruction, that is, different SRS resource sets may be triggered by different SRS request values.
Specifically, before S201, different SRS resource parameters may be configured by the RRC to define different SRS resource sets, and in an implementation, a fixed slot offset (i.e., an RRC-configured slot offset) may also be configured by the RRC for each SRS resource set. The access network device may configure the SRS resource parameter corresponding to the SRS resource set to the first terminal device for storage. The access network equipment can establish a corresponding relation between each SRS Resource set and different aperiodic SRS-Resource Trigger values, and the corresponding relation is configured to the first terminal equipment, so that the first terminal equipment records the aperiodic SRS-Resource Trigger values corresponding to each SRS Resource set; further, in step S201, after obtaining the SRS request value (i.e., SRS resource set information) included in the first control instruction, the first terminal device determines an aperiodic SRS-resource trigger value corresponding to the SRS request value in the first control instruction, and further determines a corresponding SRS resource set according to the recorded correspondence, or further obtains a corresponding SRS resource parameter, where the SRS resource parameter is subsequently used to send an aperiodic SRS.
For example, the access network device configures three SRS Resource sets, values of a high-level configuration parameter aperiodic SRS-Resource Trigger corresponding to the three SRS Resource sets are different, and the aperiodic SRS-Resource triggers corresponding to the three SRS Resource sets are respectively configured as 1, 2, and 3. In an exemplary implementation manner, an SRS request field with a value of 00 corresponds to no aperiodic SRS Resource set, an SRS request with a value of 01 corresponds to an aperiodic SRS-Resource Trigger configured as an SRS Resource set of 1, an SRS request with a value of 10 corresponds to an aperiodic SRS-Resource Trigger configured as an SRS Resource set of 2, and an SRS request with a value of 11 corresponds to an aperiodic SRS-Resource Trigger configured as an SRS Resource set of 3. If the SRS request value in the SRS request in the DCI is 11, the first terminal device may determine that the access network device triggers the aperiodic SRS for an SRS Resource set configured by an aperiodic SRS-Resource Trigger as 3, and may further obtain corresponding SRS Resource parameters, and subsequently send the aperiodic SRS. If the SRS request value in the first control instruction is 00, the first terminal device may determine that no aperiodic SRS resource set is triggered, and may determine whether the condition for sending the periodic SRS or the semi-persistent SRS is satisfied according to other information.
S202, the first terminal equipment determines the time domain position for sending the non-periodic SRS according to the first time slot offset, and sends the non-periodic SRS according to the determined time domain position.
In an implementation manner that a first terminal device determines a time domain position for transmitting an aperiodic SRS according to a first slot offset, if the first terminal device receives a first control instruction in a slot n, where the first slot offset is k, the first terminal device determines that the slot for transmitting the aperiodic SRS is a slot n + k, and further determines a symbol for transmitting the aperiodic SRS in the slot n + k (i.e., a time domain position for transmitting the aperiodic SRS) according to a symbol position in an SRS resource parameter corresponding to SRS resource set information. In one implementation, the symbol position is a position of a symbol configured to be located in one slot (i.e., a slot in which the aperiodic SRS is transmitted) for transmitting the aperiodic SRS when the SRS resource is configured by the RRC, and the symbol position may be l consecutive symbols in the last j symbols in the slot for transmitting the aperiodic SRS, for example, in NR, j may be 6, l may be 1, 2, or 4, and a symbol in which the aperiodic SRS is transmitted in the slot n + k may be determined according to the symbol position. The first terminal device further obtains SRS resource parameters, such as the number of antenna ports, the number of OFDM, and the frequency domain position, of the SRS resource set corresponding to the SRS resource set information in the first control instruction, and sends the aperiodic SRS in the n + k time slot according to the SRS resource parameters.
In an optional implementation manner, before S201, the method may further include that the first terminal device may receive first enabling information, where the first enabling information may be configured by RRC, and is used to instruct the first terminal device to determine a time domain location for transmitting the aperiodic SRS according to a first slot offset in the first parameter domain; and then after receiving the first control instruction, the first terminal equipment acquires the first time slot offset from the first parameter domain according to the first enabling information, determines the time domain position of the aperiodic SRS according to the first time slot offset, and then sends the aperiodic SRS according to the determined time domain position. That is, if the first terminal device receives the first enabling information before receiving the first control instruction, the first terminal device obtains the slot offset for transmitting the aperiodic SRS from the first parameter domain according to the first enabling information, otherwise, the first terminal device determines the slot offset for transmitting the aperiodic SRS according to the RRC configuration.
In another optional manner, after S202, the method may further include: the first terminal equipment receives second enabling information, wherein the second enabling information is used for indicating the first terminal equipment to determine a time domain position for sending the non-periodic SRS according to RRC configuration time slot offset; the first terminal equipment receives a second control instruction, wherein the second control instruction is used for triggering the first user terminal to send an aperiodic SRS, and the second control instruction comprises fourth SRS resource set information; the first terminal equipment acquires RRC configuration time slot offset corresponding to the fourth SRS resource set information according to the second enabling information; and the first terminal equipment determines a sixth time domain position according to the RRC configuration time slot offset corresponding to the fourth SRS resource set information, and sends the aperiodic SRS according to the sixth time domain position.
For example, after the first terminal device receives the second enabling information, the first terminal device determines the time domain position for transmitting the aperiodic SRS according to the first slot offset in the first parameter domain, and after receiving the second enabling information, the first terminal device does not determine the time domain position for transmitting the aperiodic SRS according to the first slot offset in the first parameter domain, but determines the time domain position for transmitting the aperiodic SRS according to the RRC-configured slot offset; and after the first enabling information is received again, the first terminal equipment determines the time domain position for sending the aperiodic SRS according to the first time slot offset in the first parameter domain.
That is, the first enabling information and the second enabling information respectively enable the first terminal device to determine the slot offset for transmitting the aperiodic SRS in different manners, and the second enabling information can be regarded as the disabling information corresponding to the first enabling information. The first enabling information and the second enabling information can be the same type of enabling information configured by RRC, and both comprise the same field type; the field types comprise an enabling field type which indicates whether the first terminal equipment determines the time domain position of the non-periodic SRS according to the first time slot offset or the RRC configuration time slot offset in the first parameter domain, and after receiving the enabling information, the first terminal equipment can identify whether the received enabling information is first enabling information which indicates that the time domain position of the non-periodic SRS is determined according to the first time slot offset in the first parameter domain or second enabling information which indicates that the time domain position of the non-periodic SRS is determined according to the RRC configuration time slot offset through the difference of values of the enabling field types, further determine the time domain position of the non-periodic SRS, and send the non-periodic SRS.
In another implementation manner in which the first terminal device determines the time domain position to transmit the aperiodic SRS according to the first slot offset, the first enabling information may be specifically used to instruct the first terminal device to determine the time domain position to transmit the aperiodic SRS according to the first slot offset and the RRC configuration slot offset in the first parameter domain. Specifically, if the first terminal device receives the first enable information before S202, the first terminal device receives a first control instruction in time domain S, where the first time slot offset is r, and the RRC configuration time slot offset of the SRS resource set corresponding to the SRS resource set information in the first control instruction is t, then the first terminal device determines that the time slot S + r + t is a time slot for sending the aperiodic SRS, and further determines, according to a symbol position in an SRS resource parameter corresponding to the SRS resource set information, a symbol for sending the aperiodic SRS in the time slot S + r + t (that is, a time domain position for sending the aperiodic SRS).
The SRS resource set information included in the first control instruction may include SRS resource set information corresponding to one SRS resource set, or may include SRS resource set information corresponding to a plurality of SRS resource sets. For example, if the aperiodic SRS-resource trigger is configured as one SRS resource set of 1, when the SRS request value in the first control instruction is 01, the first control instruction only includes SRS resource set information corresponding to one SRS resource set; if the aperiodic SRS-resource trigger is configured to have a plurality of SRS resource sets of 2, when the SRS request value in the first control instruction is 10, the first control instruction only includes the SRS resource set information corresponding to the plurality of SRS resource sets.
In a first optional implementation manner, the SRS resource set information in the first control instruction only includes first SRS resource set information corresponding to one first SRS resource set, and then the first terminal device determines a first slot position according to the first slot offset, and sends the aperiodic SRS based on the SRS resource parameter corresponding to the first SRS resource set according to the first slot position. Here, the first control instruction may be sent by the access network device to the first terminal device when the first terminal device does not expect or support to be triggered by multiple SRS resource sets simultaneously; when the first terminal device expects or supports simultaneous departure of multiple SRS resource sets, the access network device may send the aperiodic SRS to the first terminal device only when the first terminal device needs to send the aperiodic SRS for one first SRS resource set.
In a second optional implementation manner, the SRS resource set information in the first control instruction includes second SRS resource set information corresponding to each of a plurality of second SRS resource sets, so that the first terminal device may ignore the first slot offset indicated by the first control instruction, and send the aperiodic SRS according to the RRC configured slot offset corresponding to each of the second SRS resource sets. Therefore, for each of the above second SRS resource sets, the method further comprises: and the first terminal equipment acquires the RRC configuration time slot offset corresponding to each second SRS resource set according to the second SRS resource set information, determines the second time domain position corresponding to each second SRS resource set according to the RRC configuration time slot offset corresponding to each second SRS resource set, and then sends the aperiodic SRS at the corresponding second time domain position according to the SRS resource parameters corresponding to each second SRS resource set.

For example, the third SRS resource set with the smallest resource set identifier in the third SRS resource sets is used as the designated third SRS resource set, and for example, the third SRS resource set with the largest resource set identifier in the third SRS resource sets is used as the designated third SRS resource set. Optionally, a plurality of designated third SRS resource sets may be determined, and the aperiodic SRS may be transmitted according to the first slot offset. There are various specific ways of determining the designated third SRS resource set, which are not limited herein, but in any specific determination way, each terminal device in the access network device should determine the designated third SRS resource set according to the same agreed determination way.

In another possible implementation manner, the first control instruction may further include third enabling information, where the third enabling information is used to instruct the first terminal device to execute in what manner when the first control instruction includes the multiple SRS resource set information, and further the first terminal device may execute in the manner indicated by the third enabling information. Optionally, the third enabling information may be the same enabling information as the first enabling information or the second enabling information.
Optionally, if the time slot offset of the SRS resource set is not configured in advance by the RRC, the time slot offset, where the first terminal device sends the aperiodic SRS, may be implicitly indicated by the first control instruction, that is, the first parameter domain is a TDRA domain, at this time, if the SRS resource set information in the first control instruction only includes SRS resource set information corresponding to one SRS resource, the aperiodic SRS is sent according to the time slot offset in the TDRA domain implicitly indicated by the first control instruction. If the SRS resource set information in the first control instruction includes SRS resource set information corresponding to a plurality of SRS resources, that is, a plurality of SRS resource sets are triggered, in an implementation manner, the first terminal device may determine only one specified SRS resource set (for example, an SRS resource set corresponding to a low resource set identifier) from the SRS resource set information, according to a slot offset in the TDRA domain implicitly indicated by the first control instruction, send an aperiodic SRS for the specified SRS resource set, and not send an aperiodic SRS for other SRS resource sets; or in another implementation manner, if the SRS resource set information in the first control instruction includes SRS resource set information corresponding to each of the plurality of SRS resources, the first terminal device may ignore the first control signaling and does not send the aperiodic SRS; or in another implementation manner, if the first control instruction is sent to the first terminal device by the access network device when the first terminal device does not expect or support to be triggered by multiple SRS resource sets simultaneously, and the SRS resource set information in the first control instruction includes SRS resource set information corresponding to each of the multiple SRS resources, the first terminal device determines that the event is an error event, and does not send the aperiodic SRS.

The time slot offset of the first terminal equipment for sending the aperiodic SRS is dynamically indicated through the first time slot offset carried in the first control instruction, and then the time domain position for sending the aperiodic SRS is determined according to the dynamically indicated time slot offset, so that the flexibility and the diversity of the time slot determining mode for sending the aperiodic SRS are improved.
Referring to fig. 3, fig. 3 is a schematic flow chart of another aperiodic SRS transmission method according to an embodiment of the present application, where as shown in the figure, the method includes steps S301 to S305.
S301, the first terminal equipment receives a first control instruction.
The first control instruction is used for triggering the first terminal device to send an aperiodic SRS, the first control instruction includes a first parameter domain and SRS resource set information, and the first parameter domain includes a first time slot offset. Here, the first control instruction may be a slot offset that instructs the first terminal to transmit the aperiodic SRS by means of an implicit indication, and then the first parameter domain may be a TDRA domain.
The first control instruction further comprises an acquisition mode indication domain, and the acquisition mode indication domain contains one of first acquisition mode information or second acquisition mode information; the first obtaining mode information is used for indicating the first terminal equipment to obtain time slot offset from the first parameter domain; the second obtaining mode information is used for indicating the first terminal device to obtain the time slot offset from the RRC configuration parameter.
S302, the first terminal device acquires the parameters in the acquisition mode indication domain in the first control instruction.
The parameter in the acquisition mode indication field is one of the first acquisition mode information or the second acquisition mode information, if the parameter is the first acquisition mode information, S303 is executed, and if the parameter is the second acquisition mode information, S304 is executed. Optionally, the obtaining manner indication field may have one bit, and different values of the one bit represent different parameters, for example, a value of 0 is preconfigured to correspond to the first obtaining manner information, a value of 1 corresponds to the second obtaining manner information, if the value of the obtaining manner indication field in the first control instruction is 0, S303 is executed, and if the value is 1, S304 is executed.
And S303, the first terminal equipment determines the time domain position for sending the aperiodic SRS according to the first time slot offset, and sends the aperiodic SRS according to the determined time domain position.
The SRS resource set information included in the first control instruction may be SRS resource set information corresponding to one SRS resource set, or may include SRS resource set information corresponding to a plurality of SRS resource sets. For a specific implementation manner, reference may be made to a specific implementation manner of step S202 in the embodiment corresponding to fig. 2, which is not described herein again.
S304, the first terminal equipment acquires the RRC configuration time slot offset corresponding to the SRS resource set information.
Before S301, different SRS resource parameters may be configured by the RRC to define different SRS resource sets, and in an implementation manner, fixed slot offsets (i.e., RRC configured slot offsets) may also be configured by the RRC for each SRS resource set. The access network device may configure the SRS resource parameters corresponding to the SRS resource set to the first terminal device for storage. The access network equipment can establish a corresponding relationship between each SRS Resource set and different aperiodic SRS-Resource Trigger values, and the corresponding relationship is configured to the first terminal equipment, so that the first terminal equipment records the aperiodic SRS-Resource Trigger values corresponding to each SRS Resource set; further, in step S304, after obtaining the SRS request value (i.e., SRS resource set information) included in the first control instruction, the first terminal device determines an aperiodic SRS-resource trigger value corresponding to the SRS request value in the first control instruction, and further determines, according to the recorded correspondence, an SRS resource set corresponding to the SRS resource set information included in the first control instruction, and may further obtain corresponding SRS resource parameters, where the SRS resource parameters are subsequently used for sending aperiodic SRS.
S305, the first terminal device determines a fifth time domain position according to the RRC configuration time slot offset corresponding to the SRS resource set information, and sends the aperiodic SRS according to the fifth time domain position.
Here, the RRC-configured slot offset is a fixed slot offset to which the SRS resource set corresponding to the SRS resource set information is configured, and the fifth time domain position is a time domain position in which the first terminal device transmits the aperiodic SRS, which is determined according to the slot offset. Specifically, if the first terminal device receives the first control instruction in the time slot m and the RRC configuration time slot offset corresponding to the SRS resource set information is h, the first terminal device determines to transmit the aperiodic SRS in the time slot m + h, where the time slot m + h is the time slot for transmitting the SRS, and further determines, according to the symbol position in the SRS resource parameter corresponding to the SRS resource set information, a symbol for transmitting the aperiodic SRS in the time slot m + h (i.e., a fifth time domain position for transmitting the aperiodic SRS). In one implementation, the symbol position may be l consecutive symbols in the last j symbols in the slot for transmitting the aperiodic SRS, for example, in NR, j may take a value of 6, l may take a value of 1, 2, or 4, and the symbol position may be determined to be the symbol for transmitting the aperiodic SRS in the slot m + h according to the symbol position. The first terminal device further obtains other SRS resource parameters, such as the number of antenna ports, the number of OFDM, and the frequency domain position, of the SRS resource set corresponding to the SRS resource set information in the first control instruction, and sends the aperiodic SRS in the symbol corresponding to the m + h slot according to the SRS resource parameters.
The SRS resource set information included in the first control instruction may be SRS resource set information corresponding to one SRS resource set, or may include SRS resource set information corresponding to a plurality of SRS resource sets.
In a first optional implementation manner, if the SRS resource set information in the first control instruction only includes SRS resource set information corresponding to one SRS resource set, the first terminal device determines a fifth time domain position according to the RRC configuration slot offset corresponding to the SRS resource set, according to the second acquisition mode information corresponding to the acquisition mode indication field (that is, indicating the first terminal device to acquire the slot offset from the RRC configuration parameter), and sends the aperiodic SRS at the fifth time domain position. Here, the first control instruction may be sent by the access network device to the first terminal device when the first terminal device does not expect or support to be triggered by multiple SRS resource sets simultaneously; when the first terminal device expects or supports simultaneous departure of multiple SRS resource sets, the access network device may transmit the aperiodic SRS to the first terminal device only when the first terminal device needs to transmit the aperiodic SRS for one SRS resource set.
In a second alternative, the SRS resource set information in the first control instruction includes SRS resource set information corresponding to each of the plurality of SRS resource sets, so that the first terminal device may ignore the timeslot offset indicated by the first control instruction, and directly send the aperiodic SRS according to the RRC configured timeslot offset corresponding to each SRS resource set information. Therefore, for each SRS resource set, the first terminal device obtains, according to the information of each SRS resource set, a slot offset in the RRC configuration corresponding to each SRS resource set, determines a fifth time domain position corresponding to each SRS resource set according to the slot offset in the RRC configuration corresponding to each SRS resource set, and then sends an aperiodic SRS at the corresponding fifth time domain position according to the SRS resource parameter corresponding to each SRS resource set.
In a third optional implementation manner, when SRS resource set information in the first control instruction includes SRS resource set information corresponding to each of the multiple SRS resource sets, the first terminal device may select a designated SRS resource set from the multiple SRS resource sets according to second acquisition mode information corresponding to the acquisition mode indication field (that is, instruct the first terminal device to acquire a slot offset from the RRC configuration parameter), determine, according to the RRC configuration slot offset corresponding to the designated SRS resource set, a fifth time domain position for transmitting the aperiodic SRS for the designated aperiodic SRS resource set, and transmit the aperiodic SRS at the corresponding fifth time domain position according to the SRS resource parameter corresponding to the designated SRS resource set. For example, the SRS resource set with the smallest resource set in the plurality of SRS resource sets in the first control instruction is identified as the specified SRS resource set, and for example, the SRS resource set with the largest resource set in the plurality of SRS resource sets in the first control instruction is identified as the specified SRS resource set. Optionally, a plurality of designated SRS resource sets may be determined, and the slot offset for transmitting the aperiodic SRS may be determined according to the corresponding second acquisition mode information in the acquisition mode indication field. There are various specific ways of determining the designated SRS resource set, which are not limited herein, but regardless of the specific determination way, each terminal device in the access network device should determine the designated SRS resource set according to the same agreed determination way.
With reference to the third optional implementation manner, further optionally, the first terminal device does not transmit the aperiodic SRS for other SRS resource sets except for transmitting the aperiodic SRS for the specified SRS resource set.
With reference to the third optional implementation manner, further optionally, in addition to transmitting the aperiodic SRS for the specified SRS resource set, the first terminal device also transmits the aperiodic SRS for another SRS resource set. Specifically, the first terminal device may obtain RRC configuration slot offsets corresponding to the other SRS resource sets, and further determine a transmission slot corresponding to each other SRS resource set according to the RRC configuration slot offset corresponding to each other SRS resource set, where the first terminal device transmits the aperiodic SRS according to the respective corresponding transmission slot for each other SRS resource set.
In a fourth optional implementation manner, the SRS resource set information in the first control instruction includes SRS resource set information corresponding to each of the plurality of SRS resource sets, and the first terminal device may ignore the first control instruction and does not transmit the aperiodic SRS for any SRS resource set.
In a fifth optional implementation manner, the first control instruction may be that the access network device sends the first terminal device when the first terminal device does not expect or support to be triggered by multiple SRS resource sets at the same time, and the SRS resource set information in the first control instruction includes SRS resource set information corresponding to each of the multiple SRS resource sets, so that the first terminal device determines that the event is an error event, and does not send an aperiodic SRS.
It should be noted that, in the second optional implementation manner, the third optional implementation manner (including a further optional implementation manner of the third optional implementation manner), the fourth optional implementation manner, and the fifth optional implementation manner, all refer to a case that the first control instruction includes multiple SRS resource set information, and the first terminal device may execute according to a set execution mode when an execution mode is set in advance (that is, the execution mode set in advance is any one of the second optional implementation manner, the third optional implementation manner, the fourth optional implementation manner, or the fifth optional implementation manner). In another possible implementation manner, the first control instruction may further include fourth enabling information, where the fourth enabling information is used to instruct the first terminal device to execute in any of the above manners when the first control instruction includes the multiple SRS resource set information, and then the first terminal device may execute in the manner indicated by the fourth enabling information. Optionally, the fourth enabling information may be the same enabling information as the first enabling information, the second enabling information, or the third enabling information.
In the embodiment of the application, a first terminal device receives a first control instruction, where the first control instruction is used to trigger the first terminal device to transmit an aperiodic SRS, the first control instruction includes an acquisition mode indication field, and when the acquisition mode indication field is first acquisition mode information, the aperiodic SRS is transmitted according to a slot offset implicitly indicated in the first control instruction, and when the acquisition mode indication field is second acquisition mode information, the aperiodic SRS is transmitted according to a slot offset configured by an RRC, so that a slot offset for dynamically indicating transmission of the aperiodic SRS is achieved, and flexibility and diversity of a transmission slot determination mode of the aperiodic SRS are improved.
